Huh. I always just assumed that hydrogen cars were internal combustion engines, in which they filled a combustion chamber with H2 and burned it off. I'm surprised it's nothing like that.

Today I learned.

Internal combustion engines tuned for hydrogen fuel also exist. However the benefit of a fuel-cell vehicle is being able to recharge the batteries with the fuel-cells, regenerative braking, or at a charging stations.
